This report recommends policies and actions to improve the return on investment the U.S. government makes in sponsoring research and development (R&D) at the Department of Energy's (DOE) seventeen National Laboratories ("Labs"). While the Labs make a unique and significant contribution to all of the Department of Energy's missions, the authors develop the idea that for the Labs to fully support DOE's energy transformation goals, their R&D management practices need to be updated to better reflect current research into innovation systems and management. They also highlight the necessity of Lab interactions with industry in order to impact the nation's energy infrastructure investment, which is, for the most part, privately held.

Xi is now not only the most powerful leader of China since Mao. He is also the most ambitious leader of any country today. In the past five years, he has proved himself the most effective in advancing his nation’s position in the world. And among all of the competitors on the international stage, he is the most likely to leave a lasting mark on history.

The Water-Carbon Trade-off of China's Coal Power Industry

Abstract

The energy sector is increasingly facing water scarcity constraints in many regions around the globe, especially in China, where the unprecedented large-scale construction of coal-fired thermal power plants is taking place in its extremely arid northwest regions. As a response to water scarcity, air-cooled coal power plants have experienced dramatic diffusion in China since middle 2000s. By the end of 2012, air-cooled coal-fired thermal power plants in China amounted to 112 GW, making up 14% of China's thermal power generation capacity. But the water conservation benefit of air-cooled units is achieved at the cost of lower thermal efficiency and consequently higher carbon emissions intensity. We estimate that in 2012 the deployment of air-cooled units contributed an additional 24.3–31.9 million tonnes of CO2 emissions (equivalent to 0.7–1.0% of the total CO2 emissions by China's electric power sector), while saved 832–942 million m3 of consumptive water use (about 60% of the total annual water use of Beijing) when compared to a scenario with water-cooled plants. Additional CO2 emissions from air-cooled plants largely offset the CO2 emissions reduction benefits from Chinese policies retiring small and outdated coal plants. This water-carbon trade-off is poised to become even more significant by 2020, as air-cooled units are expected to grow by a factor of two to 260 GW, accounting for 22% of China's total coal-fired power generation capacity.
